LEONARD TILTON, OF BROOKLYN, NEV YORK.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 297,032, dated April15, 1884.

Application filed October 19, 1883.

To all whom, it may concern:

Be it known that I, LEONARD TILTON, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Holder forVVindow-Blinds, of which the following is a full, clear, and exactdescription.

The object of this invention is to provide a convenient and practicaldevice to be attached to window sills and blinds for holding the blindsat any desired position; and the invention co nsists, principally, of ajointed arm adapted to be attached to the blind, and pivoted to a studadapted to be secured upon the window-sill, the arm'and stud beingprovided with means for locking the arm and the sections thereof at anydesired position for holding the blind open or closed or at anyintermediate position.

The invention also consists of the special means for locking the arm andof the special construction of the device, all as hereinafter fullydescribed and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 shows in plan view my invention applied to the window sill andblinds. Fig. 2 is a sectional elevation of my new blindholder. Fig. 3 isan inverted sectional plan view taken on the line as w of Fig. 2, thebottom plate, 70, being removed; and Fig. 418 a perspective view,showing the means employed for attaching the outer end of the holder tothe blind, and the position the arm assumes when the blind is heldentirely open back against the wall of the building.

My new and improved window-blind holder is composed of the jointed arm Aand post or stud B, to the pin b of which the arm A is pivoted, and bywhich stud the device is adapted to be attached to the window-sill O byscrews 0 e, passing through the plate 0 of the said stud B, as shown inFig. 1.

The arm A is composed of the two sections a a, which are hinged togetherby the pin 93.

The section a is solid and curved outward at its outer end, and formedat its outer end with the upwardly-projecting knob f, which runs betweenthe flanged plates D D, secured to the window-blinds E, as shown'clearlyin Fig. 3. The inner pivot end of the section a is en- (No model.)

larged, and formed with the teeth 9 and stop lips h h, for the purposeshereinafter described. The section a ol' the main arm A is not solid,like the section a, but is made hollow, or formed with thedownwardly-projecting side plates, a? t. It is also formed with the lugsj j, which are screw-tapped to receive the screws jj, for securinginplace the bottom plate, Ir, for bold ing the slotted sliding dogs G Gand springs Z l in place in the said section, as shown in Fig. 2, and inits centerthis section a is cupped, as shownat m, and in this cup isplaced the double-acting cam F, which, when turned to the position shownin full lines in Fig. 3, acts simultaneously upon the adjacent ends ofthe dogs G and G, for forcing them outwardly against the tension of thesprings 11, for causing the dog G to engage with the teeth 9 of thesection a, and the dog G to engage with the teeth 9, formed in thecollar 0 of the stud or post B, for locking the sections a a at anydesired position. The springs Z Z are placed in the slots 0 0 of thedogs G G and act between the lugs j j and rear ends of the said slots,so that when the cam F is turned to the position shown in dotted linesin Fig. 3 the springs will force the dogs simultaneously to ward eachother, disengaging them from the teeth 9 9, thus leaving the sections aa free to be turned upon their pivots for shifting the position of theblind, the lips h h serving, in connection with the ends of the flangesi i, to limit the pivotal movement of the section a, and the stop-lips hh, formed on collar 0, serving also, inconnection with the opposite endsof said flanges, to limit the pivotal movement of the section a.

The cam F is formed with the opposite corresponding shoulders, 12 p,which act upon the rear ends ofthe dogs G G, for forcing them out ward,and with the stop lips q g, which come against the ends of the dogs forpreventing the cam from being turned too far in either direction; andthe said cam F is secured to the lower end of the bolt H, 011 the upperend of which is secured the crank I, for operating the bolt, and throughit the cam F.

J is a jamnut placed upon the upper end of the bolt H, above the crankI, for locking the bolt H, and consequently the cam F, in thepositionshown in full lines in Fig. 3, for locking the sections a a ofthe arm A in any position The flanged plate D, secured to the blind,-

overhangs the knob f, while the plate Dserves to support the outer endof the section a and to hold the knob f under the plate D, and

- also to furnish a chafe-plate for the outer end of said section tomove against in opening and closing the blind, as will be understoodfrom Fig. 4.

hen the blind is to be held closed or at any intermediate position, thesection a of the arm A will be held in line with the section a, as shownclearly in Fig. 1.

Constructed in the manner described, it will be seen that the device isvery effective for its purpose, is Very convenient, and easily operated.

Although I have shown and described my invention as applied towindow-blinds, it will be understood that it is likewise applicable forholding doors and other hinged objects open or closed, or at any desiredposition.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The window-blind holder herein shown and described, consisting of thejointed arm A and stud B, and combined with means, substantially asdescribed, for locking the sections of the arm A, at their pivotalpoints,-at any desired position, as and for the purposes set forth.

2. The sections a and a, hinged together and to the stud B, the studbeing formed with notches g, and the section a with notches g, incombination with the dogs 'G G, springs Z, and cam F, all arranged tooperate substantially as set forth.

3. The section a of the arm A, formed with the flanges '1 i, incombination with the section a, formed with the stop-lips h h,substantially as and for the purposes set forth. W

4-. The stud B, formed with lips h it, in combination with the section aof the arm A,for1ned wit-h the flanges 2' i, substantially as and forthe purposes set forth.

5. The hollow section a of the arm A, inclosing the sliding dogs G G,and springs Z Z, in combination with the cam F, arranged between thedogs, and adapted to be turned by crank I and locked by jam-nut J,substantially as described.

(5. The cam F, arranged between the'adjar cent ends of the'dogs G G, andformed with the stop-lips q q, substantially as and for the purposes setforth.
